Is it better to croak() or to die() when something bad happens in Perl?

Question

perlcritic complaints that the following code, some boilerplate DBI stuff that works perfectly fine, should croak instead of die:

# Connect to database
my $db_ha

From http://www.perlmonks.org/?node_id=685452

You use die when the error is something you or your code didn't do right. You use croak when it's something your caller isn't doing right. die "error: $!" indicates the error is on the line where the error occured. croak "error: $!" indicates the error is on the line where the caller called your code.

In this case, the error (connection error to DB) has nothing to do with the caller and everything to do with the line making the connection, so I would use die.
